You can join me at the museum for free, but you have to make a reservation in advance by calling 202-334-1201 or emailing ksm@nas.edu. Or you can watch the livestream here, thanks to the folks at the American Society for Microbiology, which collaborates with the Koshland Museum. You can even ask questions via Twitter if you tweet them to @microbeworld or use the hashtag #koshland. We’ll be having a long Q & A session, and someone will be reading the questions from Twitter.
